Distal Scaphoid Excision for Chronic and Nonchronic Scaphoid Fracture Nonunion.
Article in Journal of hand surgery global online, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: The indications for distal scaphoid excision are limited to localized wrist arthritis surrounding the scaphoid, as a result of scaphoid nonunion advanced collapse or scapho-trapezio-trapezoid joint arthritis. The procedure historically has led to relief of symptoms and improvement in strength. Our aim was to examine the outcomes of this procedure in patients with scaphoid fracture nonunion. Methods: This is a single-center retrospective case series of 12 consecutive patients who underwent distal scaphoid excision after scaphoid fracture nonunion. Patients were divided into the following two groups based on nonunion chronicity: chronic (more than a year) and nonchronic (less than a year). Clinical and radiographic data were examined using descriptive statistics. Results: Our cohort consisted of 12 patients, 10 men (83%) and 2 women (17%), with a mean age of 37.6 ± 13.6 years. Eight patients had a chronic scaphoid fracture nonunion (six had a neglected scaphoid fracture and two had a nonunion after scaphoid open reduction and internal fixation with bone graft), and four patients had a nonchronic fracture nonunion (two had failed cast treatment and two had nonunion after scaphoid open reduction and internal fixation with bone graft). Before surgery, all patients complained of pain and four had numbness (all in the chronic group). After an average of 21 weeks after surgery, seven patients (58%) reported continued pain, two patients reported ulnar side pain, and one underwent arthroscopic synovectomy. All patients who started with a normal radiolunate angle continued to have a normal angle, whereas patients who had dorsal intercalated segmental instability prior to surgery persisted with it after surgery, except for a patient who underwent midcarpal fusion and had their radiolunate angle corrected. Conclusions: Distal scaphoid excision is an effective procedure for carefully selected patients with periscaphoid wrist arthrosis. Patients with recent scaphoid fractures that failed treatment may also be treated with distal scaphoid resection. Type of study/level of evidence: Therapeutic V.
